C-Section and Celiac link

So apparently studies are now beginning to show the link between babies born under c-section that have celiac disease opposed to those born vaginally. I've often times heard that babies born under extreme circumstances were at higher risk for allergies, but never understood why.

I will be very interested to hear more about this. I know that Matthew was born via c-section after he went in to distress prior to induction and often wondered if that was partly to blame for his numerous allergies.
